Self-illuminating fabricated solid material objects

ABSTRACT

Self-illuminating fabricated solids, e.g., a pavers, driveway stones, building blocks, or statuary having an assembly, of optical fibers having second ends contained within a first end of a receptacle, embedded within the solid object so that the first end of the fibers visually terminate at the object&#39;s surface. The second end of the receptacle is exposed at the object&#39;s surface to reversibly receive and position a reversibly powered light source in operative contact with the fiber&#39;s second ends guiding light from the source through the fibers to the surface of the fabricated object providing for self-illuminating seasonal designs, informational text, or advertising. A plurality of designs in various colors may exist on a single object. These durable objects have a long life as surface exposed fibers wear with the surface of the object and worn-out light sources are easily and rapidly replaced.

BACKGROUND

The present invention relates generally to self-illuminating objects andmore particularly to self-illuminating, fabricated, solid objectsembodying designs, greetings, or information in a choice of colors.

The background information discussed below is presented to betterillustrate the novelty and usefulness of the present invention. Thisbackground information is not admitted prior art.

Examples of materials that can be fabricated into solid objects includecement, concrete, plaster, fiberglass, glass, and plastics, to name justa few. These materials may be fabricated into a solid by the setting(i.e., the solidification or hardening) of a liquid or a suspension, bypressing a powdered material into a mold, or any similar knowntechniques. Fabricated solids can be shaped into a vast variety ofobjects from an artistically sculpted lawn or garden decoration topaving stones for a patio, walkway, or driveway. Historically, lightingfor these surfaces has been mainly from spotlights or appropriatelyplaced lights. There have been some attempts to provideself-illuminating fabricated solid objects, but most efforts in thisdirection rely on the presence of one or more cavities within the solidobjects in which a light source system is housed. These cavities createa structural weakness and a place for moisture or other contaminants tocollect.

An example of these illuminating solids include illuminating blocks thatare to be used mainly on the periphery of walkways. The light sourceproviding the illumination is placed within transparent, flexible,tubing-like material that is positioned within a recessed channel thatis open to the top surface of the stone. To provide power to the lightsource, an electrical junction box must be inserted into a second, muchlarger cavity that opens to the bottom surface of the block. Thesesystems, however, present several problems. To avoid moisture fromreaching the lighting units, filler must be placed within the flexible,tube-like material around the light source. The filler, of course, alsomust be transparent so as not to prevent the light from emanating fromthe surface of the object. The rather large cavity required to house thepower system creates a structural weakness within the fabricated solidobject. The relatively soft, transparent material used as a surfacecover creates additional problems. The soft material cannot withstandthe damaging effects of both physical and chemical weathering to whichit is exposed, nor can it stand up to the wearing effects of pedestrianor vehicular traffic. What is sorely needed is the means to provide aself-illuminating solid object having a surface that is impervious tothe damaging effects of both physical and chemical weathering andimpervious to the daily wear that occurs on surfaces on which people andvehicles move.

Other attempts to provide illuminating surfaces rely on wiring that mustbe embedded into a surface topping, such as asphalt or concrete, as thetopping is applied. Cavities must be cut into the surface topping sothat the wiring can be connected to a light producing assemblage thatmust be fitted into each cavity. This type of system use a soft,plastic-like material placed over the light elements through which thelight can emanate, but this approach suffers from the same limitationsof poor durability as discussed above. Additionally, these systems canonly be used in the initial installation of a walkway or a roadway. Whatis needed is the means to provide for self-illuminating fabricated solidobjects that can be used in new and previously installed walkways ordriveways, or on any other type of existing hard surface, whether thesurface is horizontal, vertical, or inclined.

While some of these attempts to provide for in-pavement lighting useLEDs (light emitting diodes) as a light source, they also rely on asystem of optical lenses and prisms to direct the light. These lensesand prisms, however, result in glass or other transparent or translucentweak material being located on the surface of these rather complexhousings. To avoid damage from overhead foot or vehicular traffic theseunits can only be placed on the edge of the walkway or driveway. What islacking in the art is a homogenous solid matrix incorporating LED lightsources within a fabricated solid object that can be used in new orexisting walks or driveways and that will last for the life of the solidfabricated object.

Furthermore, there have been attempts to provide illuminating solidmaterials made in or conveying designs to meet almost any occasion, suchas a holiday, birthday, seasonal event, wedding, birth, etc. These arelimited, though, by the fact that they must be fabricated from cleartransparent materials such as methylmethacrylate, Lexan®, acrylic, orthe like. Moreover, these solid materials must be etched or grooved todisperse light from the light source that must be inserted into a cavityformed in the material. These materials are inherently soft in the sensethat they would not be practical for use where they would becontinuously exposed to harsh weather conditions or more than occasionalphysical wear and tear. There is still an unmet need for a means toprovide for fabricated hard material objects having incorporatedillumination that is durable under even harsh conditions and can bepresented with almost any desired design, or multiple alternatingdesigns, in almost any desired color.

Recently, solar powered stepping stones have been described. These,however, still rely on a sealed housing provided with a soft-materialtranslucent lens through which the solar powered light can diffuse. Thetranslucent material is preferably an acrylic resin which will notsupport heavy vehicular or pedestrian traffic. What is missing from theart are fabricated resistant solid material objects that areself-illuminating, wherein the power for the illumination is provided bysolar power, and where the solar-powered object maintains its durabilityeven under harsh conditions including the damaging effects of physicaland chemical weathering and heavy vehicular and pedestrian traffic, andcan be offered in almost any desired design in almost any desired color.

Recently stepping stone illuminating systems having a light sourceembedded within the material from which an object is made, have beendescribed. While these systems are generally durable when exposed to thetraffic expected when used as walkway or driveway building materials,they do not provide any means for replacing a worn-out, damaged, orimperfect light source. In the recently described systems, all opticalfibers, electronic circuitry, and light sources are permanently sealedand permanently imbedded within the material used to form the object,such as a paving block. To replace a light source in this system, theentire block would have to be replaced. Because the electrical supplymeans extend outside of the block, this system also suffers from thedisadvantage that the paving blocks must be installed over acompressible aggregate, such as finely crushed gravel, in order toprovide for the external wiring. Although this system allows for the useof a variety of colored light sources, once a color for the lights in agiven block is chosen, there is no way to change the color of thelights, such as from orange for Halloween celebration to red and greenfor a Christmas theme, without replacing the entire block. Furthermore,this system makes no provision for a choice of design of a given blocksuch as the choice to change from a pumpkin to a Christmas tree—again,the only choice is to change the entire block.

Thus, it has been shown that all of the present known attempts toprovide for a self-illuminating fabricated solid present problems thatinclude solids that require chambers, grooves, channels, pockets orpanels of significant size for housing a light bulb or other lightsource from which light is emitted through a soft material located onthe top surface of the solid. Additionally, none of these devicesprovides for an illuminating fabricated solid object, such as a pavingblock or stepping stone that has the strength, versatility andfunctionality of a concrete block or stepping stone, that provides for alighted surface that includes various colors, patterns, or designs oflight which may cover either part or the entire surface of the block orstone, and where the light source, the color, and the design can bechanged or replaced easily and rapidly without having to replace theentire object.

In view of the foregoing, it is desirable to provide forself-illuminating, fabricated, objects, such as self-illuminating pavingblocks or stones that emit light from their surfaces while maintainingthe strength and durability expected from a comparable concrete paver orstepping stone, and that can do so at low cost while being attractive inappearance, versatile, functional, and durable. Such self-illuminatingobjects should be able to be manufactured in almost any desired shape,with almost any design, or designs, in almost any desired color, wherethe colors, design, and light source can be rapidly and easily changedor replaced without the need to replace the entire object, and where thefabricated hard objects can be used on either hard or compressiblesurfaces, as desired.

SUMMARY

The present invention satisfies the heretofore unmet need forself-illuminating, fabricated, solid objects, such as self-illuminatingpaving blocks, building stone, or statuaries that emit light from theirsurfaces, while possessing strength comparable to a non-illuminatingconcrete, or other suitable material, paving blocks, building stones, orcast statues, providing for inexpensive to manufacture,self-illuminating fabricated solid objects, that are attractive,versatile, functional, and adapted to include one or more patterns ofvarious colored light and where the colors, design, and light source maybe rapidly and easily changed or replaced without the need to replacethe entire object, and where the fabricated hard objects are useable oneither hard or compressible surfaces, as desired. Self-illuminatingobjects made according to the teachings of the present invention requirelittle or no maintenance.

The present invention achieves the above and more by setting forth novelself-illuminating fabricated solid objects, such as paving stones orstatuary, wherein the objects have any known, or yet to be known,optical fibers embedded within, where one end of the optical fibers areexposed at a visually exposed surface of an object, and while secondends of the optical fibers are contained within a first end of an openreceptacle also embedded within the object except for a second end ofthe receptacle that is exposed at a surface of the object. The exposedreceptacle end is adapted to reversibly receive a reversibly poweredlight source to achieve contact of the fiber's second ends with thelight source so that light emitted from the light source is therebyguided from the source through the fibers to the surface of thefabricated object providing for any colored self-illuminating patterns,seasonal designs, informational text, or advertising. A plurality ofdesigns in various colors may exist on a single object. These durableobjects have a long life as surface exposed fibers wear with the surfaceof the object and worn-out light sources are easily and rapidlyreplaced.

The self-illuminating objects are formed by casting, molding, orpressing, or any other method that results in the making of afabricated, solid object. The objects can be made of any material havingproperties amenable to the final intended use of the self-illuminatingobject, such as concrete or cement if it is desired to manufactureself-illuminating paving or building blocks or stones. Cement orconcrete, as well as clay, plastic, plaster, fiber glass, and glass maybe employed to manufacture statuary, memorial stones, or name plaques,for example. The manufacturing material may be opaque, translucent, ortransparent.

The receptacle can be of any shape that will accommodate a desired lightsource. The receptacle can be of any material that will provide for thedegree of protection desired for the light source. These choices will,of course, be dictated by the intended final use of theself-illuminating fabricated object.

The light source can be any light source. In the examples discussedbelow the preferred light source is a light emitting diode (LED). Thelight source can be powered by traditional AC electrical sources,electrical batteries, or other powering source, such as solar energy. Ifa LED light source is employed, the system requires only low power, suchas a 12 volt source and is thus economical to run and energy efficient.

DETAILED DESCRIPTION

Referring now, with more particularity, to the drawings, it should benoted that the disclosed invention is disposed to embodiments in varioussizes, shapes, and forms. Therefore, the embodiments described hereinare provided with the understanding that the present disclosure isintended as illustrative and is not intended to limit the invention tothe embodiments described herein.

The present invention is directed towards a self-illuminating fabricatedsolid, such as a paving stone or statuary. The illumination is providedby having one or more optical fibers embedded within the solid objectwith one end of the fibers adaptedly exposed at the object's surface toprovide for a desired design or pattern, which design or pattern isexpressed by the light emitting from fibers exposed at desired places onthe surface of the object, while second ends of the optical fibers arecontained within a first end of at least one open receptacle that isalso embedded within the object except for the opening at the second endof the receptacle, which opening is exposed at a surface of the object.The exposed open end of the receptacle reversibly receives at least onereversibly powered light source which mates with the fibers' second endsfor the purpose of guiding light from the light source through thefibers to the surface of the fabricated object providing formulti-colored, self-illuminating seasonal designs or patterns,informational text, or advertising. A plurality of designs in variouscolors may be present on a single self-illuminated solid object. Thesedurable objects have a long life as surface exposed fibers wear with thesurface of the object and worn-out light sources are easily and rapidlyreplaced.

Turning now to the drawings, FIGS. 1 a-1 c illustrate one exemplarypreferred embodiment of the present invention. FIGS. 1 a and 1 b,transparent perspective views of self-illuminating fabricated solidobject assembly 10, illustrate paving block 12 with self-illuminatingtext “HELLO” visible on the surface on the surface as shown in FIG. 1 a.Paving block 12 comprises visually exposed surface 14, base 16 andsurface 18 having at least one aperture 30. The transparency of thedrawings allows for illustration of optical fibers 20 as they occurembedded within the matrix of the paving block. Also illustrated isembedded receptacle 22 having first end 23 and second end 25. During thefabrication of solid object assembly 10, optical fibers 20 andreceptacle 22 are positioned within the initially liquid or otherwisemalleable material, used in the formation of paving block 12, so as toprovide for one end of optical fibers 20 to be visually exposed on asurface of object 10 while the other end of optical fibers 20 aresecurely enclosed in first end 23 of receptacle 22. Receptacle 22 isdesigned to prevent any damage to the light source, such as fromlightning, static discharge, and over voltage conditions. Second end 25of receptacle 22 is exposedly positioned in aperture 30 of receptacle 22for easy accessibly after the paving stone is formed into a solidobject. Positioned thusly, second end 25 is adapted for the reversibleacceptance of reversibly powered light source 40 (see FIG. 1 c) toprovide for mating of light source 40 with the ends of optical fibers 20that are enclosed in first end 23 of receptacle 22. Light source 40 isillustrated with affixed means for providing power 46 to light source40. Mating light source 40 with the ends of optical fibers 20 that areenclosed in first end 23 of receptacle source provide means for lightemitted from light source 40 to be guided from light source 40 to theends of the optical fibers that terminate on the visually exposedsurface of the fabricated solid object providing for self-illuminationof the fabricated solid object.

FIG. 1 c illustrates first end or light bulb 42 of light source 40positioned for its reversible insertion into second end 25 of receptacle22 SO that the reversibly powered light emitted from light source 40 isbrought into intimate contact with the second end of optical fibers 20and, thus, caused to travel along the length of the fibers from thesecond end of the fibers enclosed in first end 23 of receptacle 22 tothe first ends of fibers 20 that are exposed on a visible surface of aself-illuminating solid object.

FIG. 2, a non-transparent view of a self-illuminating fabricated solidassembly, shows a paving block according to the teaching of thisinvention as it appears ready for use. The ready accessibility of secondend 25 at aperture 30 of receptacle 22 ensures that light sources may beinserted and removed easily and rapidly, as desired. As mentioned above,aperture 30 is not required to be as large as it is in theillustrations. It need be only as large as required to hold receptacle22. The illustrations are designed for clarity of explanation.

Light sources may suffer from usage or from age or may be defective assupplied. In any of these instances, a replacement of the light sourcemay be necessary. In the invention as disclosed, replacement of a lightsource is accomplished rapidly and easily. The old light source isremoved from receptacle 22 by a slight pull or tug. Once the old lightsource is removed, a new light source is easily and rapidly insertedinto receptacle 22. Alternatively, a light source may be in perfectworking condition, but one may desire to change the color emitted by thelight source. Any known light source may be used, but in the preferredembodiment illustrated, the light source is a light emitting diode (LED)which, of course, is a low-powered light source and is inexpensive tooperate. Traditional bulbs, if desired, may also be employed.

In the preferred embodiment illustrated, the power source is from a lowpower voltage source, or alternatively relies on the corrective actionof a resistor and or rectifier and/or inverter, and on traditionalwiring. The power source used to provide power to the light source,however, can be any known power source. For example, solar power is alsocontemplated as a power source.

The preferred self-illuminating fabricated solid object assembly 10comprises block 12 cast from concrete, cement, or any other moldablematerial that will provide the properties desired for the block asdescribed, or for any of other desired fabricated self-illuminatingobjects that can be made according to the present invention. The castingor molding material may be added to the mold after the optical fibersand the receptacle holding one end of the fibers have been arranged inthe mold. If this is the manufacturing process employed, then it is atthis time that the ends of the optical fibers that will terminate at thesurface of the object are positioned so as to achieve the desiredpattern that will be described by the light that will emanate from thefibers exposed at the object's surface. The fact that theself-illuminating fabricated solid comprises a negligible amount of voidspace from the addition of the fibers and the receptacle to the object,the resulting objects, such as a paving stone or block, retainsproperties that are comparable to those of objects that are cast ormolded without the addition of the fibers and the receptacle. Regardlessof the material used or method for making employed, any of thecontemplated self-illuminating fabricated solid objects as claimed maybe of virtually any shape, including interlocking, radius or traditionalsquares, spheres, and all other polygonal shapes, animal, people,imaginary characters such as angels, gargoyles, or unicorns, waterfountains of any of the above and other designs, and so forth. In thepreferred embodiment illustrated, the paving block 12 has asubstantially square or rectangle shape and may, of course, includerounded corners and edges to prevent chipping. The cast or moldedmaterial may be colored in the manufacturing process by the addition ofpigments to achieve almost any desired color. In addition, the topsurface 14 of the paving block 12 may be sealed with any knowntransparent or translucent surface treatment to form a water resistantlayer while preserving the illumination effect. Further, the pavingblock 12 may be manufactured having almost any desired surface textureand/or pattern, such as slate, cobblestone, brick, or the like. Thus, itcan be seen that the present invention provides for a self-illuminatedsolid surface that is impervious to the damaging effects of bothphysical and chemical weathering and to the daily wear that occurs whenthe surface is subject to both pedestrian and vehicular traffic.

FIG. 3 illustrates a self-illuminating fabricated solid object having aseasonal pattern created by the light emitting ends of the opticalfibers that are exposed on the visible surface of the object. Nearly anydesired pattern, design, numbers, or letters may be formed on thesurface of an object.

FIG. 4 illustrates a self-illuminating fabricated solid object havingtwo seasonal patterns emitting light (see 24 a and 24 b for example) onits visible surface. Each pattern is formed by a unique set of opticalfibers in working association with a related unique receptacle, such as22 a or 22 b. In the example illustrated, one may insert an orange lightemitting source into the receptacle that is operatively connected to theoptical fibers whose visually exposed tips describe the pumpkin pattern,and at another time, one could insert a light source that emits greenlight into the receptacle that is operatively connected to the opticalfibers whose visually exposed tips describe the holiday tree. During thetime period in which one does not desired to display a specific pattern,the light source providing the light required for the pattern is simplyremoved from the relevant receptacle. If desired, a plug or cap may beinserted into the receptacle to protect it from any harmfulenvironmental conditions. It is further contemplated that eachself-illuminating object assembly may comprise a plurality ofpredetermined patterns on its visually exposed surface, as desired. Itis also further contemplated that a regulating switch be used toalternate the power from one light source to another if a flashing orblinking display is desired. It is still further contemplated that a setof switches and/or timers are used to simulate motion, such as when aplurality of designs are on one object, or single designs on a pluralityof objects, and where the on/off action of the power to the variousdesigns creates an image of motion. This can be visualized, for example,as an arrow that appears to move toward an entrance way when in realityit is a series of self-illuminating arrows in a series of walkway pavingblocks that are sequentially connected and disconnected to a powersource by the regulating switches and timers.

When a series of self-illuminating solid objects, such asself-illuminating paving stones or blocks, are placed on unconsolidated,compressible material, such as sand or crushed stone, the wiring used toconnect the system to a power source and the wiring that is used tointerconnect the blocks may conveniently be buried in the sand orcrushed stone. If, however, it is desired to place self-illuminatingfabricated solid objects on a hard surface, there is the problem ofwhere to place the power providing wires. FIG. 5 illustrates a means forplacement of self-illuminating blocks on a hard surface. To accomplishthis, each object, such as a paving block, that is to be placed on topof a hard surface comprises at least one beveled or notched base edge50. The beveled or notched edge provides a space just sufficient toaccommodate any required electrical wiring. If there are a series ofadjacent blocks, such as when the blocks are used to construct a patiofloor, a garden walk, or a driveway, the small, but sufficient spacecreated by the bevel or notch provides a protected conduit for anyrequired wiring. The connective wiring is protected from the damagingeffects of traffic or weather. In fact, because no wiring is exposed onthe surface, self-illuminating blocks made according to this inventioncan be placed even on surfaces that are likely to suffer from seasonalsnow plowing. Note, that, if desired, self-illuminating fabricated solidobjects, such as blocks or stones, are just as amenable to installationin a vertical position to form a wall surface or a fence. In thisinstance, the wiring is also protected by positioning the wire withinthe protective conduits created by beveling or notching at least onebase edge. The conduits provide not only for the physical and chemicalprotection of any required wires but provides for additional aestheticappeal; e.g., tucking the wiring in the grooves assures that the wiringis not exposed in an unsightly manner. The bevel or notch, like theaperture provided for the receptacle, is minimally sized so as not toreduce the strength of the block. Therefore, it can be seen that thepresent invention provides for a system that can be used on anypreviously formed hard surface, whether the surface is a horizontal,vertical, or inclined, as well as on unconsolidated materials, new orold.

As mentioned earlier, the self-illuminating fabricated solid objects maybe formed into almost any desired size and shape and of almost any colorto address any aesthetic. One popular use for concrete or cement is toprepare statuary, especially the statuary so coveted as lawn and yarddecoration. FIG. 6 illustrates a self-illuminating fabricated solidobject in the form of a lion. Such statuary is often seen in theentrances to homes. Attractive in the daylight, such statuary is hardly,if at all, visible at night. In fact, it is conceivable that suchstatuary could pose a tripping hazard if approached in the dark. FIG. 6illustrates how an attractive piece of statuary can also provide forillumination at night. The eyes 26 of the lion are defined by lightemitting optical fibers according to the teaching of this invention.Statuary made according to this invention provides a welcoming and safebeacon to a home's entrance.

The self-illuminating fabricated object described herein has a multitudeof uses. An object can be used alone, such as using a singleself-illuminating building block, to provide for self-illuminating housenumber signs and/or name plaques that are set into a building wall. Inmany cases, a plurality of self-illuminating, fabricated objects can beused together to construct large area or large volume, self-illuminatingobjects. For instance, if an object is shaped as a paving stone, theself-illuminating objects can be used to form walkways, driveways,walls, and fences. Such paving stones can be fabricated to any shapeincluding squares, rectangles, circles or any other regular or irregularpolygon. Alternatively the paving stones can be shaped to mimicnaturally occurring pavers. When used in this way, these pavers havestrength and endurance comparable to that of non-self-illuminatingpavers. They can be walked over and can easily sustain the weight ofmost vehicles. Another novel use for this invention is to insert lightsource 40 into apertures other than those found in fabricated objects,such as apertures fabricated into columns, railings, steps, edgeportions of porches and decks, window trim, doors, cupboard faces,molding, picture frames, furniture, and the like. Using the light sourceof this invention in this way is limited only by a materials inabilityto comprise apertures adapted for receiving light sources according tothe teachings of the present invention. The aperture(s) may be arrangedto reproduce or complement a light pattern or design in a near-byself-illuminated fabricated material object, such as the paving stonesof a walk or driveway. Such a continuity of light, along the pathtraversed to a secluded entrance way, for example, would reduce theincidence of falls or missteps when approaching difficult to see steps,a turn in the walkway, or the like. Such a continuity of light wouldalso act as a design element to induce, or invite, persons to follow thelights to enter a building, such as a shop or a nightclub.

As each of the at least one optical fiber is set into the fabricatedsolid so that only the first end terminates flush with, and thus isvisible at, the visible surface of the object, the fibers are protectedby the material into which they are cast. This means that the fiberswill wear at the same rate as the fabricated material and, thus, couldbe expected to last the lifetime of the fabricated material object.Although the fibers and the receptacle by which the fibers are held arepermanently sealed and imbedded within the body of the self-illuminatingobject, the light source, which is the only part of the assembly thatmight suffer with age, is removable and, thus, is easily and quicklyreplaced, without the necessity of replacing an entire object. Becauseof the low cost of the optical fibers, the light source, and standardelectrical wiring, the cost to manufacture and maintain theself-illuminating objects is only minimally more than the cost ofmanufacturing and maintaining objects without the self-illuminationassembly. Maintenance costs can be kept low by utilizing timers orphotoelectric power or switches.

The illuminating fibers can be arranged to provide for nearly any typeof desired patterns, designs, or informational messages. During lowlight hours, a self-illuminating paver or block could be used to warnpeople that a step must be traversed. The warning could be simply lightemanating from a random pattern, a nearly solid bar of illumination, orby arranging the fibers to describe the work “STEP”. Accordingly, theentrance to a drive way, house numbers, the name of a home's occupants,all can be self-illuminating utilizing a horizontal or vertical surface.

Light sources are available in a wide variety of colors. A neutraldesign or pattern can be made to reflect a holiday or a particularcelebration by simply changing the color of the light source. Reds andgreens can be used to celebrate a holiday such as Christmas, purple andyellow for Easter, red for Valentines Day, and so forth. The lightsources are not expensive and are particularly easy to change so thesespecial effects are easy for almost anyone to achieve. Additionally,most light sources, especially LED light sources are long-lasting andcome in a large variety of colors that do not change or diminish withage or temperature.

When self-illuminating solid object assemblies are contemplated for usein a low traffic area, the object could be fabricated from a softertransparent or translucent material resulting in a vast number oflight-emitting design options.
